I installed my printer today (Epson Expression Photo XP-750) and I saw that Windows 7 was asking me to choose between two different printing devices, even thou they both belong to the same physical printer. The printer was connected over Wi-Fi (not the Wi-Fi Direct mambo jambo) to my router.
But notice how the addresses are different for the two devices. In one of the addresses it says "WSD". I have looked it up and it's a Microsoft API. It stands for Web Services for Devices. I kindly asked Epson tech support what this was, and they either didn't know the answer to that or didn't care to explain. They only gave me a vague answer. My experience is that manufacturers don't give a damn, as long as the thing works. To be fair, most users don't give a damn either.
So how do you figure then, what's the difference between the two here then? It's not in the users manual, so as a user I guess I'm left to figure this out on my own, eh? I'm not looking to write my own programs using this API, I would just like to know the difference between the two options (the practical implications) so I can make an informed decision.
Why does the name look so funny in the first one? The last few characters before the parenthesis looks like a MAC address. Why would you want to include the MAC address in a printer name?
